Letters Patent No. 914,956, dated June 29,1869.

IMPRovsD RAILWAY-CAR TRUCK The Schedule referred to in these Letters Patent and making part of the same.

To all whom it ma/y concern:

Be it'known that I, JOHN M. McGnHU, of Milton, in the county of Santa Rosa, and State of Florida, have invented a new and useful Improvement in Railroad-Oarsyand I do hereby declare that the following 'is a full, clear, and exact description thereof, which will enable those skilled in the'art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a top view of my improved car` upoufthe track.

Figure 2 is a vertical cross-section of the same.

Similar letters of reference indicate correspondingl parts.

My invention has for its object to furnish a simple and conve-nient car, designed especially foruse' in hauling lumber and similar uses, in places Where ordinary roads are diflicult of construction, and where ordinary railroads, it' built, would be too expensive; and

1t consists in the construction ofthe car, as hereinafter more fully described. l

The frame of the car is formed by connecting the frames of two two-wheeled trucks, A and B, to each other, as shown in iig.- 1, so that the car may couveniently pass around bends, or turns of the track.

The broad wheels O C, of the forward truck A, are made slightly cone-shaped, and placed upon theiraxles with their bases toward the central line of tlie car, so that Vthe tendency may be to keep the car directly over the centre of thetrack.

- The rear truck B is provided with the equally broad E'heels O C', having concave-peripheries, as shown in By forming the wheels of the forward truck conesh'aped, the car may beeasily drawn back upon the rails, incase of becomingdisplaced by accident or otherwise.

A bolster, D, is pivoted to the central frame-piece,

or beam of each truck, so that the frames may be free to get out of line with each other in passing around bends in the track, without disturbing the loading.

E is the tongue, to which the mules or other draughtanimals are attached, and which is rigidly attached to the forward truck-frame A, so as toguide the car, and keep it upon. the track.

This car is designed for use exclusively on rails formed of rough or round timber, which are laid down without any special regard to accuracy of gauge, the construction ofthe wheels enabling the car to be readily kept upon thel rails.

I am aware that car-wheels having bevellcd edges have heretofore been constructed, but as these form no .partof 4my invention, I do not,- therefore, claim them; but

I claim as new, and desire to secure by Letters Patent- V The railroad-ear, consisting of the two two-wheeled trucks A and B, each provided with the swinging bolvster D, the forward truck A being supported on the cone-shaped wheels O vC, arranged with their basesv toward the cent-ral line of the car, and the rear truck B provided with the wheels C C,.haviug concave perpheries, all constructed as described, whereby the car is adapted for use on tracks of irregular gauge, for

the purpose specified.
